# Cold-compressed and freely sintered virgin PTFE flat gasket manufacture

Global applicability for all following rule families: This attributional method manufactures one drawing-specific unfilled non-expanded virgin PTFE flat annular gasket at a declared CN site. Begin with the whole purchased conventional homopolymer granular moulding powder, verified for cold compression; receive/store/condition/screen, uniformly charge and cold-press a preform, demould, freely sinter in an electrically heated ventilated batch oven, cool under the actual controlled programme, directly dry-turn/bore/part and deburr the billet into solid one-piece gaskets, inspect/test and uniquely first release. Retain real failed batches, warm-up, idle, start/stop, extraction, cleanup, rework and utilities. Subsequent actual FG storage/packing/handling/dispatch is a separately reported original-cohort service account. [daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023; doing-ptfe-oven]

Exclude filled or chemically modified PTFE; expanded or structured PTFE; paste lubricant extrusion; ram or isostatic moulding; hot coining/water quench; purchased sheet/billet conversion; sheet skiving and sheet-cut gaskets; melt injection; elastomer or metal-composite seals; spring-energized seals; welded segments; resin synthesis; coatings/printing; medical implantation; oxygen-service cleaning; fuel-fired sintering; bought-finished-gasket repacking; installation/use/end of life. A real departure requires renewed applicability and complete atomic exchanges.

## 1. Scope and Applicability

This attributional method manufactures one drawing-specific unfilled non-expanded virgin PTFE flat annular gasket at a declared CN site. Begin with the whole purchased conventional homopolymer granular moulding powder, verified for cold compression; receive/store/condition/screen, uniformly charge and cold-press a preform, demould, freely sinter in an electrically heated ventilated batch oven, cool under the actual controlled programme, directly dry-turn/bore/part and deburr the billet into solid one-piece gaskets, inspect/test and uniquely first release. Retain real failed batches, warm-up, idle, start/stop, extraction, cleanup, rework and utilities. Subsequent actual FG storage/packing/handling/dispatch is a separately reported original-cohort service account. [daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023; doing-ptfe-oven]

Daikin establishes conventional granular powder and cold-press/free-bake processing; Teadit independently describes direct machining after cooling into sealing products; Doing establishes real electric-resistance batch-oven capability and also fuel-fired alternatives. This is transparent complementary technical synthesis, not one SKU/recipe/factory/current order. No brochure density, particle size, pressure, temperature, time, power, weight, yield, emission factor, creep result, torque, service life or certification is a default. Daikin NEW modified grades and the Teadit expanded/structured variants are countercontexts; Tables1/2/4/8, Figs3–8 and adjacent notes do not establish interchangeable materials or universal programmes. The supplier warning mentioning HCl is not proof that pure PTFE contains chlorine; retain actual precursor/speciation evidence. [daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023; doing-ptfe-oven]

Exclude filled or chemically modified PTFE; expanded or structured PTFE; paste lubricant extrusion; ram or isostatic moulding; hot coining/water quench; purchased sheet/billet conversion; sheet skiving and sheet-cut gaskets; melt injection; elastomer or metal-composite seals; spring-energized seals; welded segments; resin synthesis; coatings/printing; medical implantation; oxygen-service cleaning; fuel-fired sintering; bought-finished-gasket repacking; installation/use/end of life. A real departure requires renewed applicability and complete atomic exchanges.

| What | Supply a complete flat annular industrial sealing gasket for its declared joint |
| How much | 1 kg of new uniquely first-released bare gaskets |

Declare every qualifier in the foreground package and preserve the entire finished_gasket card restriction; generic identity does not establish service equivalence, material/provider compatibility or an accepted mapping.

## 4. Measurement and Unit Rules

| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Use actual bare net mass at unique first release; measure moisture/conditioning and exclude all packages. Use cp_release and calc_q; no per-item mass or density guessed. |
| numerator_units | all inventory rows | row-specific | row-specific | Preserve raw units and rate/total flags. Apply calc_units and evidenced allocation before calc_normalize_once; exactly one A/Q normalization. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Whole purchased conventional unfilled virgin PTFE granular moulding powder at receipt; include actual inbound freight and upstream powder supply |
| starting_condition_role | foreground collection gate; upstream supply remains linked background |
| product_classification_scope | Narrow36990 industrial PTFE flat gasket subset; classification is not method approval |
| recursive_input_rule | Internal powder/preform/billet/rework transfers retain cohort history and cancel on consolidation; bought released gasket is not a new raw input route |
| upstream_dataset_requirement | Match delivered whole powder grade/form/route and every actual supply/service state; preserve transport and package inclusions without duplicate upstream purchases |
| disclosure | Declare complete failed/zero-output loads; WIP and non-WIP physical stock and every inherited exchange vector; distinct first-release and FG service gates; all real species/streams and gaps |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| b_route | all manufacturing | Include raw-powder handling, actual cold pressing, all oven ramps/holds/cooling and ventilation, direct machining, cleanup, failed trials, rework, testing and first release. A purchased finished gasket is not a substitute for this route. Add each actual unlisted exchange with a specific identity; no residual other-material bucket or unsupported zero. | daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023; doing-ptfe-oven |
| b_q | manufacturing and FG | Q is the sum of net kg at each unique NEW first-quality-release event after machining/testing. Reinspection, dispatch, return or repeated repair-release creates no new Q. Closing FG already in Q is a custody stock, never a second manufacturing output. Keep actual packaging/storage/handling/dispatch and return-inspection services as incremental original-cohort accounts; merging cancels the internal release transfer and preserves the single production burden. | teadit-ptfe-gaskets-2023 |
| b_vectors | all cohort stocks | Keep disjoint opening/closing raw powder, green preform, sintered billet, machined WIP, FG and rework physical quantities with a historical vector for EACH exchange. Independently retain non-WIP press/lathe/oven equipment service, hydraulic/gear oil, coolant-water and refrigerant charges and vectors, including idle/maintenance. Allocate real utility consumption or a measured-consumption equivalent with inventory correction once; never subtract stock twice or erase inherited burden. Returned gaskets carry original production once; only actual additional repair materials/energy and old component wastes are new. A changed composition/geometry requires renewed applicability. | daikin-ptfe-moulding-2019; jrc-ilcd-2010 |
| b_packages | each package | For EACH incoming drum/liner and outgoing bag/carton/tape/pallet independently: opening empty + opening attached WIP/FG + opening reusable + purchases + external returns received = closing empty + closing attached WIP/FG + closing reusable + packages on gross physical shipments + external returns sent + waste. Stock categories are disjoint. Internal reuse cancels, is neither another purchase nor Q nor automatic coproduct. Preserve original burdens and real repair/replacement materials and wastes; supplier-included packaging is not purchased again. Separate gross physical movement from net financial shipments. | jrc-ilcd-2010 |
| b_physical | manufacturing/FG/consolidated gates | Reconcile complete physical mass and relevant C/F and actual other-element balances independently of measured molecular species. No single residual may determine two unknowns. Keep free water, actual reaction water, vapour and any structure/phase-bound water distinct; PTFE morphology/density change does not create water. Measure FG moisture separately. Native TFE CAS116-14-3 denotes monomer, never PTFE dust CAS9002-84-0. Actual external liquid heat-exchange return is a Product output with temperature/enthalpy and supplier water/energy agreement; actual oily condensate is separate waste. Do not invent steam/boilers or count a returned-water burden twice. | daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023 |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| prepare | Receipt and powder preparation | required | actual operations within section1 including zero output | foreground | 1 kg reference flow |
| form | Cold preforming and electric free sintering/cooling | required | actual operations within section1 including zero output | foreground | 1 kg reference flow |
| machine | Direct dry machining and first release | required | actual operations within section1 including zero output | foreground | 1 kg reference flow |
| utilities | Actual utilities and equipment service | required | actual operations within section1 including zero output | foreground | 1 kg reference flow |
| service | Actual post-release FG services | conditional | actual original-cohort services only | foreground | 1 kg reference flow |

Internal powder/preform/billet and release-to-FG transfers are stage ledgers, not repeated external purchases. Each card describes one physical exchange; conditional means verify actual presence/absence, not assume zero. Add every actually present unlisted material/species with an atomic card and protocol, including real cleaning agents, filter housing, cooling treatment or repair components.

###### Actual atmospheric oxygen uptake (`oxygen`)

Conditional independently evidenced oxygen uptake CAS7782-44-7 only if actual oxidative species chemistry consumes it. It is not purchased compressed air, not inferred by fitting two unknown emissions. Balance the actual selected physical gate, with pass-through air/water recorded separately where crossing the declared gate; no assumption that all PTFE loss oxidizes.


Native Elementary Resource from air / renewable element resources from air, CAS7782-44-7, reference Mass index0/factor1 and kg. Use only independently measured ordinary molecular-O2 uptake from ambient air at this declared gate, not an oxygen emission, a purchased gas supply or an assumed fraction of bulk air. Broad native liquid/ion/isotope/phase aliases do not change the actual gas; no fixed geography, grade, quantity or oxidation extent follows. Gross pass-through air and other phases remain separately observed and non-additive with net uptake; do not subtract atmospheric flow without a matched physical/species ledger.

###### First-released complete flat gasket (`finished_gasket`)

Exactly one drawing-specific one-piece conventional unfilled non-expanded virgin PTFE flat gasket, cooled and directly dry-machined to its declared flange application. Native Product/Mass/kg at plant CN, for installation during assembly; no CAS, grade, component mix or manufacturing route is prescribed by the native record. Its rubber36270 classification is a disclosed taxonomy inconsistency with the otherwise generic gasket/seal name and synonyms; it is not a rubber-material constraint or a36990 mapping. This qualified use does not authorize elastomer O-rings, mixed seals or installed equipment. Retain drawing, powder form, cooling/machining and sealing acceptance evidence. Packaging excluded; unique first release only.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| a_scope | all allocation rules | The following hierarchy is conditional on an actual allocation-required attributional situation. Manufacturing-source capability is not LCA allocation evidence. | jrc-ilcd-2010 |
| a_subdivide | allocation-required attributional cases | First independently assign dedicated lots/materials/meters and real or virtual subdivision. Do not turn a mixed oven into one uniform mass factor: identify each batch function, actual load geometry and time-temperature heat demand, standby/extraction and other causal demands. Keep service burden attached to its actual released cohort. | jrc-ilcd-2010 |
| a_physical | remaining shared exchanges | For each still-shared exchange establish a determining physical causal relationship to each co-function and quantify its actual extent; evidence it separately for electric heat, machine drive, extraction, water and other streams. Mere mass correlation, nominal power, production value or arbitrary physical/economic choice is insufficient. | jrc-ilcd-2010 |
| a_residual | only genuinely residual allocation | Only genuinely unallocated remainder after subdivision and exchange-specific determining physical causality uses co-function market value at the common process gate in its actual condition and the same representative period. Record quantities/prices/quality/state, gate consistency, uncertainty and sensitivity; not retail finished-gasket prices versus wet-scrap prices at another gate. No fixed fraction or automatic recycling/substitution credit. Waste treatment service and an accepted coproduct require explicit separate status and burdens. | jrc-ilcd-2010 |
| asset_manufacture_conservation | existing capital/reusable manufacture attribution | Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory. |  |

## 8. Foreground Data Collection, Calculation, and Quality Rules

Protocols collect undivided raw records. aggregation_rule states only the final target basis; it performs no division. Cards and aggregation read the same stored calc_normalize_once result. No source supplies actual site quantities.

### Data Collection Protocols

For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Store raw values without division; retain supplier-included constituents as subaccounts. | kg | each lot and stock cut-off | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_release | machine | unique first release | foreground_record | cohort; drawing; lot; serial release event; bare net kg; tare; count; moisture; conditioning; acceptance specification and actual tests; original Q | Use calibrated weighing of bare accepted gaskets or count-verified homogeneous lots, excluding packaging. Sum unique NEW first-release net kg as Q. Keep reinspection/return separate. Count-to-kg uses measured configuration-specific net mass, never density or a guessed item weight. | kg | each acceptance and cohort close | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_energy | utilities | actual manufacturing electric load | foreground_record | meter; raw start/end kWh; actual power/time only if rate; batch geometry; programme; ramps/holds/cooling; idle/startstop/failed/cleanup; causal allocation; utility inclusions | Meter differences without division; integrate actual power rates once with matching time units.

Convert integrated volume using this material density at its actual state; integrate only true rates. Record measured species and water independently; preserve external return as Product where applicable. | kg | each circuit interval and stock cut-off | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |

Keep actual gross acquired mass, actual outward recovery/unused transfers, spent waste and independently measured leaks distinct from the service-burden vector. Retain disjoint non-WIP physical stocks and every inherited exchange vector. Use independently measured consumption or a proved equivalent stock/vector correction once, not both. An unused outward transfer carries only its evidenced remaining vector; spent oil/filter, leakage or treatment-bound discharge does not automatically cancel the upstream burden already consumed in service. Do not subtract every physical outward quantity as unused return or reduce a real acquisition/waste/leak card by allocation. Retain original stock lineage, actual composition/assay, service attribution and additional handling/treatment burdens separately; no missing mass is automatically an air emission. | kg | each service event and cut-off | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_air | utilities | external compressed air | foreground_record | actual supplier; original total/rate volume; pressure; temperature; humidity; reference conditions; energy inclusion; leaks | Preserve metered reference-state volume and source-specific state correction. Do not multiply integrated volume by duration; internal generation cancels with real own utilities retained. | m3 | each actual interval | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_waste | machine | each specific waste | foreground_record | stream; preform/sintered state; source lot; raw wet/dry mass; moisture; contamination; handler; actual recovery/disposal; retained polymer and inherited vectors | Weigh each actual physical waste stream and split captured powder, sintered turnings, failed articles and composite filter waste; reconcile independently with raw/WIP and physical mass. Internal reuse is a transfer retaining energy/losses. | kg | each transfer and closing stock | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_emission | form | actual individually identified species | foreground_record | species; CAS; molecular identity; source event; air compartment; stack/fugitive; original concentration and gas total/rate volume; pressure/temperature/humidity; time only for rate; capture; measured water and C/F balance | Use independent analytical identity and calibrated species-specific mass; integrated gas volume times compatible concentration once, time only if a true rate. Keep precursor and downstream hydrolysis species at their true gates, not duplicated. Total fluoride/VOC/COD cannot stand for a particular molecule. Missing coverage remains unknown. | kg | representative full runs including failures | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_packaging | service | each named package and destination | foreground_record | article; composition; provider; original count and measured kg; purchases; included supply; external returns received; gross shipment outward; external return sent; waste; disjoint opening/closing empty/attached-WIP/FG/reusable stocks and every historical vector; repair old/new masses | Weigh/tare actual single articles or homogeneous lots and reconcile b_packages separately for each material. Keep original burden once and physical gross directions; internal reuse is not another purchase. A real repair component and its old waste require separate rows and historical vectors. | kg | every purchase/movement/repair and stock cut-off | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_service | service | original-cohort incremental services | foreground_record | original cohort Q; service interval; undivided meter data; opening/closing FG kg/moisture and production/service vectors; gross dispatch; original delivery reversal; returns; inspection/repair; real new/old component mass and vectors; service-WIP/non-WIP | Retain raw physical custody and actual incremental load. Original burden follows the original gasket once; reinspection/repair is not new production. Keep original-delivery reversals and actual replacement/new-component-old-waste vectors; materially changed product requires applicability review. Disclose incomplete services. | kWh | every movement/service interval | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_freight | prepare | actual inbound road service | foreground_record | origin; destination; actual load mass tonnes; actual loaded distance km; mode; route; vehicle; empty leg; provider inclusions | Collect whole shipment transport service using actual t times actual km once before allocation; preserve original records and any supplier inclusion. Other actual modes require atomic rows. | tkm | each shipment | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |
| cp_equipment | utilities | each durable press/oven/lathe | foreground_record | machine identity; composition; disjoint opening/closing in-service physical units N0/N1; actual gross acquisitions N_in; external returned acquisitions; actual outward Product handovers N_out; complete retirements N_retired; actual repair additions/removed parts; original and remaining upstream per-exchange vectors; separately evidenced service-demand vector allocated to each first-release cohort or later service interval; capital boundary | Keep raw physical counts and service-burden vectors as distinct linked ledgers. For the same complete-machine identity close N0 + actual gross acquisitions + actual external returns received = N1 + actual Product handovers outward + actual complete retirements, with other actual directions separately named and internal movements cancelled. Do not reduce a retained physical machine because some upstream burden was assigned to service, and do not reduce a genuine acquisition count by a service fraction. Under the disclosed capital boundary, attribute actual service per exchange using evidenced demand and original/remaining stock history once, separately from acquisitions and actual repair parts/removed parts. Link each service allocation to either manufacturing first release or a later original-cohort interval; never repurchase old assets or re-charge already assigned history. Item(s) and item are the same count unit with factor1; no guessed kg/machine, lifetime, equal repair mass or default depreciation. | item | each event and reporting cut-off | complete declared cohort/period with relevant opening history | actual site; each lot/equipment/circuit/receiver | per 1 kg reference flow | original calibrated records; independent identity/state and vector reconciliation |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| calc_q | finished_gasket | Q = sum of unique NEW first-quality-release bare net kg from cp_release; exclude repeat inspection, return and dispatch; include measured actual retained moisture consistently. Closing FG is already part of Q. | cp_release; cohort_id | Q | teadit-ptfe-gaskets-2023 |
| calc_normalize_once | all inventory rows | For Q > 0, z_i_c = A_i_c / Q once. Before this sole division convert original numerator units/states and integrate only true rates, then apply evidenced assignment/allocation. Manufacturing burden vectors retain attributable current loads plus opening minus closing disjoint unreleased raw/WIP and eligible non-WIP historical vectors, corrected once. Never subtract closing FG production vectors: every newly first-released gasket is already in Q even if still stored; prior released opening FG is not new current production. Service burden vectors retain only original-cohort incremental service and eligible service-stock vectors, keeping assigned production history fixed. Physical acquisition, external return, gross shipment, emission and waste cards use actual direction quantities in their own mass, volume or item unit as A_i_c, independent of consumed-service burden allocation. In particular complete-machine inputs are actual gross acquisitions and retirement outputs actual handovers, not service-equivalent fractional machine purchases; retained old equipment can have zero acquisition and a positive independently attributed service vector. A newly acquired whole machine remains its actual acquired count even when only part of its upstream vector serves this cohort. Do not add gross acquisition-provider burdens and the same stock-attributed service vector twice; retain linked physical and burden views. Use independently measured consumption OR a proved equivalent lineage-specific stock/vector correction once, without subtracting all spent/leaked/wasted outward mass as unused transfer. Q for service is the original release cohort kg, never net dispatch or repair release. Cards and aggregation only read this same z_i_c, without another division. At Q=0 retain real loads, stocks and vectors and issue no unit result. | A_i_c; Q; cohort_id; service_interval | z_i_c | daikin-ptfe-moulding-2019; teadit-ptfe-gaskets-2023; jrc-ilcd-2010 |
| calc_units | all inventory rows | Original numerator conversions: g to kg uses0.001; t to kg uses1000; kWh to MJ uses3.6 from the verified native energy unit group. Use measured material-specific density at the independently documented state only for a real volume-to-mass conversion. Count-to-mass uses measured net lot mass/count of the same configuration. Integrated liquid/gas volume is not multiplied by time; true rates are integrated once. | raw_quantity; raw_unit; measured_state; measurement_record | converted_raw_quantity | daikin-ptfe-moulding-2019 |
| calc_physical | all physical gates | For each disjoint physical gate independently reconcile opening + actual external inputs = closing + actual external outputs + actual measured transformations; cancel internal transfers. Keep separate measured component/element balances and species-based reaction/water checks, including actual air/oxygen/water if a reaction consumes them. No residual-fitting two unknowns or equating polymer dust with monomer; add actual unlisted atomic exchanges before closure. | physical_stocks; measured_inputs; measured_outputs; independent_species; moisture | gate_balance | daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023 |
| calc_packages | all package rows | Apply b_packages to each single package identity with actual physical directions and disjoint stocks. Carry original vector once, record real new repair parts/old-part wastes, cancel internal reuse and never count packages in net gasket Q. | cp_packaging; package_id; opening_stock; closing_stock; physical_movements | package_balance | jrc-ilcd-2010 |
| asset_manufacture_share | existing capital/reusable manufacture attribution | For each included original asset manufacture vector B, f_current = u_current / D only after the persistent ledger verifies the supported whole installed-service denominator, all beneficiaries and prior assigned shares. Attribute f_current * B once to the actual beneficiary before the existing single reference normalization. Check prior_shares + all current/new beneficiary shares <= 1; carry the remaining original balance. Capacity revisions reconcile the historical ledger. Full physical asset/packaging mass and actual gross stocks/returns never receive f_current. Unknown D or history leaves the final attributed result unavailable, without suppressing actual repair/replacement/service burdens. | asset_id; original_B; u_current; D; historical_beneficiaries; prior_shares; capacity_evidence | conserved attributed manufacture vector |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| dq_identity | all bound and unbound rows | Verify all native names/synonyms/comments, CAS, form, route, geography, compartment, type, every property and exact referenced unit chain. Generic identity proves neither actual supplier compatibility nor quantitative data. Track unresolved auxiliary UUIDs without replacing an atomic exchange or automatic draft. | complete direct identity and supplier/measurement evidence |
| dq_programme | powder through release | Use actual grade/shape-dependent programmes and release testing; source example matrices, density, shrinkage and creep plots are not factory measurements or service certification. | actual programme/lot traces; calibration; drawing and independent specification |
| dq_complete | all ledgers | Retain zero-output, failed, idle, cleanup and rework; all WIP/FG and non-WIP physical/vector histories, raw numerator provenance, ordinary unresolved supplies and missing service/emission coverage. Unknown is not zero or pass. | raw meter and stock records; species evidence; uncertainty and coverage register |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| v_basis | reference and all rows | Exactly one finished_gasket Product output links the1kg reference. EN/ZH qualifiers, Q gate, rows, unit basis and one normalization agree. Collection stores undivided raw data; aggregation is the target label, not another operation. Q0 yields no unit result. | teadit-ptfe-gaskets-2023 |
| v_material | powder/forming/machining | Reject applying this method to a conflicting powder form, modified/filler/expanded polymer, altered hot-coining/isostatic/ram/skiving route or purchased finished article. Verify actual first release and scope; raw-to-product route must remain complete. | daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023 |
| v_native | native UUID bindings | Apply each entire card restriction. The seal generic name cannot infer rubber material from its classification or establish a36990 mapping. TFE monomer CAS116-14-3 cannot represent PTFE9002-84-0 dust; air-unspecified bindings are replaced by verified actual compartments when known. CN below1kV grid user-side supply only. Unresolved actual flow/provider/unit compatibility remains explicit. | daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; teadit-ptfe-gaskets-2023; doing-ptfe-oven |
| v_balance | manufacturing/FG/non-WIP/packages | Independently verify physical mass/element closure and actual species/reaction-water evidence. Reconcile every package direction/stock and non-WIP charge vector, inherited production/service separation, opening/closing WIP/FG moisture and actual repair new/old components. No duplicated closing-FG output, internal purchase, automatic coproduct or residual-fitted emission. | daikin-ptfe-moulding-2019; daikin-ptfe-m17-2016; jrc-ilcd-2010 |
| v_allocation | shared burden | Document the actual attributional allocation need, dedicated/virtual subdivision, exchange-specific determining causality and only genuinely residual common-gate same-state contemporaneous market values; no fixed physical/economic split or automatic credit. Missing scientific evidence or unsupported relationships remain pending review. | jrc-ilcd-2010 |
| validate_asset_manufacture_conservation | existing capital/reusable manufacture attribution | For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness. |  |
